If it is a new book that you think the library should own, you can suggest it via our Suggest a Purchase page (with as much or as little information as you know). There's no guarantee that we'll be able to buy it, but we do take your recommendations seriously. If the title you suggested does get purchased, it takes about 8 weeks to order, receive, and process the title.
You can also request an InterLibrary Loan, where we borrow the book from another library. It can take two to four weeks for the materials to come in. It is also possible that we will be unable to get the book. To submit a request, print the form and work with a Librarian to fill it out.
